To alli/)hom it may concern:

Be it known that we, Josnrn T. Uns- BING and HOLMES MARSHALL, citizens of the United States, residing at Cleveland, Ohio, and New Yorlcity, New York, respectively, have invented certain new and useful Im provements in Computing-Machines, of which the following is a clear, full, and

. exact description.

'in machine of our prior patent heretofore,

re erred to, provided with the devices of this invention; Fig. 2 is a section on the line 2.-?2 Fig. 1 showing the units and tens members of our machine looking in the direction of the arrows; Fig. 3 is a plan view on line 3 3 Fig. 1 shown as taken between the nprights, hereinafter referred to; and Fig. 4 is a detail of the rel setting Wheels.

es shown in the drawings, each structurel member or unit of the machine may be comoosed of a frame l in which an indicator shag 2 and an operating shaft 3 is located. 0n the indicator shaft there are located wheels d, one of which only is shown in the drawings, but it will be understood that a number of these are usually supplied in rnachines of this character, and on the shaft 3 there arelocated a number of wheels having different numbers. of teeth, the wheel 6 f shown having nine teeth. These wheels constitute connecting mechanisms normally incapable of causing the operation of the indicator from the operating shaft. e. hey 7, one of a series, is rovided to control a' dotent 8 pivoted at 9m brackets 10, inthe top plate ll. of the machine and it consti-4 tutes a selective mechanism for permitting the engagement of the gear i of the indicator with the wheel 6 of the operating shaft 3, all as shown in our before-mentioned United States patent. y v

Upon the indicator shaft 2 there is carrind between uprights12` andv 13, three disks, liek il constituting a controlling mwns 'next denomination.`

permitting a carrying to the next higher denomination, and provided with one tooth 15 to operate a controlling lever 16 of the gear wheel, preferably of ten teeth, is slidable on the shaft 'ont normally held from sidewse motion by a detent spring 18,

Disk 17, which is a' operated Vby such a controlling lever 16,'

' and said lever being operated from a single tooth disk 14 mounted on an adjacent `shaft vof the next lower denomination. Disk 20 having a cnt-away portion 21, as shown in Fig. 4, and known as the indicator resetting disk being in fact a mutilated gear is also mounted on the said indicator shaft. The .toothed indicator 1re-setting disk 20vis slidable on its shaft and is normally heldV from sliding by a detent spring 22 providedw-ith en arm 23. Springs 24 and 25 on two levers .26 and 27 shown inl Fig. 2 serve to tend to,

shift such disks 17 and 20 always sidewise 75 upon their shaft. Independently of 'the pressure caused by spring 24, disk 17 is dprovided with a coil spring S which tens to throw said disk to the right, Fig. 1. This spring S therefore acts on .disk 17 when lever 26 is thrown to the left to release the detent 18, as will be more particularly described hereafter.

On the operating shaft 3 there are mounted two disks 28 and 29 fixed in position, one

a disk 28 having one tooth 30 known as a carrying forward disk, and the other 29, a

vmutilated gear wheel having a cntfaway portion 3l, and known as a rie-setting disk. The re-setting disk 29,011 the shafts of all denominations may be the same in position, but the carrying forward disk 28 on the different shafts should have their single teeth 30 in advance position as shown in Fig. 2. lt is observed from this ligure that the lefthand disk-28 on the shaft of a lower .denomination has its single tooth nearer to the position in which it operates the wheel -17 than does the adjacent disk of a higher denomination. Thusthe disks on the shafts of the several denominations will come consecutively into play beginning with the loW-.

est. The arrow shows the direction of rotation in order that the carryin shall be done successively from right to le t as one faces the machine, so that lfgures 9, '9, *9, werein- .dieatedv andv one added, the 1 would first be transferred to vthe tens column by the tooth 30 of the units column,and then, and not until then, would the transfer from the tens column to the hundreds column occur.

Our re-setting Wheels`20 and 29 as shown in Fig. 4 are so positioned With relation to the indicator' shaft, that upon a complete operation of the machine they Will rotate their various shafts forward to indicate in each column the figure 9. In other Words, if the figures 237 occurred as a result of the last operation, the units Wheel would be set forward two-spaces, the tens six spaces and the hundreds seven spaces," until nine occurred in each space Without any possibilityof carrying any ligure. It is then that our improved mechanism of'this invention comes into play. The spring S when the re-setting lever 41 has been operated forces the gearwheel 17 into the path of the single tooth 30 on the units disk 28, and this tooth of the units disk is so positioned that it will come-into play just as, or just after, the resetting mechanism has taken the position of Fig.. 4, thus adding to the units column by a tenth of a revolution and causing that column to rotate to zero position, releasing by the tooth 15 of the disk 14 the carrying mechanism of 'the nexthigher column in which the tooth 30 of its disk 28 will rotate that column one tooth and a normal carrying of one Will be effected across the entire machine, thusy re-setting it to zero.

The resetting disk 20 of the units column is released from the spring detents 22 by the oscillation of the re-setting lever 26 carryingthe lu 33 engaging the detent 23 and a lug 32 to e struck and operated by a pin 33X on an arm 37, said arnrbeing rocked by an arm 34 controlled in turn by a longitudinally moving shaft 38 operated by a lever 41 on shaft 40 and rock arm 39. 'Ihe carrying disk'17 is released from its detent 18 in the same Way by the lug 41 on the arm 26 raising the free end of the detent. The re-setting disk20 of the tens, hundreds, etc. units are all released in the same manner as inthe same disk of the units column, but the disks 17 o f tens,`hundreds, etc. are released in the saine manner as'shown in our prior patent bythe tooth 15 and lever arm 16 of the next lower column.
